The ventilator to which the present inven-l tion relates is one particularly adapted to be usedV in the window opening of a vehicle or automobile of the closed body type. The movement of the vehicle creates an air flowV eXteriorly of the vehicle body, and the ventilator is adapted to supply Ventilating air to `the vehicle bodyand ca usethewithdrawal of air therefrom.

Referring more particularly to the drawings the Ventilator comprises three main plates or sections, one plate 10 being of channel shape and preferably` formed of a single sheetl of metal bent into .such form, as shown. This plate has short vertically extending top'and bottom edges 11 and 12 which are slidingly received inthe flanged edges 13V Y and" 14vof the two fiat vertical plates 15V and 16, which are mounted in alignment with one another along the open side of the channelplate 10.; The vertical plates 15 and 16, are: preferably somewhat greater in length-than half the length of the channel plate 10 and the inner oradjacent ends ofl these flat plates are normally spaced apart so that their outerends extend some distance beyond the ends ofthe channelplate 10. Each ofthe plates. l5 andv 16 is provided with anoutwardly bent: tongue or `baflie 18 which isof spond-ingto the interior ofthe channell plate 1() so as to block the passage of air nally through the channel plate at an inneror intermediate'part thereof. The bafflesy 18 1 longitudfiv a shape corre'- are preferably formedv by bending the inner plates 15- and 16 at rightl angles, and lit neatly in.` the channel plate 10, but without binding. A coil spring 19 is fastened to baille 18, and toa rod`20 which is fixed in theY en d of the channel plate 10, it being unl derstood that each of the flat plates is thuis. i.

yieldingly connected to thel channel plate, the ksprings being effective to normally urgel the fiat platesoutwardly and away from the; central portionv of the channel. plate, to an eX- tent limited by thecompressedcondition of the spring which is thus effective to alscfprevent the complete separation of the flat plates from the channel plate 10.

The channel plate 10 and the tvvo flat plates 15 and 16 thus form a horizontally extending elongated passage which is so mounted preferably at the top of a Window opening of a moving vehicle as to extend out into the rush of air past the vehicle; so that air is caused to flow into the forwardly facing open end 22 of the ventilating passage, and is Withdrawn from the rearwardly facing opening 23 thereof. The direct travel of air through the ventilating passage is prevented however by the provision of the bailies or tongues 18, and each of the flat plates 15 and 16 is provided With a series of ventilatingopenings 2li in con'miunication with the interior of channel plate 10 so that air is caused to iioiv into the vehicle through the plate 16 for the supply of fresh air to the interior of the vehicle, andv air is Withdrawn from the vehicle through the openings in the plate 15, at the rear of the ventilator. the plates 15 and 16, andvvithin the outlines of the channel plate 10 are screens 25 of Wire mesh, one screen being fastened directly to each of the nat plates to prevent the entrance of dirt or any small particles of matter which may be iioating around in the air, into the vehicle. Y

The ventilator is adapted to be used in the opening of a Window or door, having a vertically adjustable Window glass, and is preferably mounted atV the top ofthe Wineow opening Where it is particularly effective and Where it does not interfere with the vision of the occupants of the vehicle. As shown in Figs. 1-to 4, the Window frame embodies uprights 27 and 28 and the top cross member 29,

Within Which is mounted-the Window glass 30; the construction preferably being such thatthe Window glass is guided vertically in compressible guide strips 31 offelt, rubber or the like,received or held in the customary U-shaped metal channels 32 in the frame members. The upper edge of the Window7 is adapted to be received in a correspondingly shaped compressible guide strip 31, when the Window is closed. The Window is adaptedV to be lovvered from its closed position by means of any suitable mechanism, such as is Well-known in the art. The plates 10, 15, and 16 forming the ventilating passage are adapted to be mounted in the Window opening by means of extension plates 34 one of-Which is provided in the end of each of the flat plates 15 and 16. These extension plates are formed of flat sheet metal With their outer ends Apreferably bent inwardly as indicated at 35, and these bent ends are adapted to be received in the glass receiving guide strips 31 so that the Ventilating passage formed ofthe channel plate 10 and the flat Vplates 15 and 16 is positioned entirely outside of the path of movement of the vvindovv glass.` The extended Along the outer side of each ofl Latines ends 35 are thin enough so that the glass is not prevented from being moved along between these ends, Which are preferably bent and shaped to receive the vertical edge of the glass and form a guide for the latter. As previously mentioned the springs 19 yieldingly hold the flat plates 15 and 16 apart and the ventilator may be readily mounted in its proper position by merely pressing the plates 15 and 16 together to reduce the total length of the ventilator and then, after placing the bent ends 35 of the extension plates Within the Window opening, the springs are permitted to contract and expand the ventilator horizontally against the Window frame. The springs 19 thus maintain at all times a considerable vpressure on the bent ends 35 hold- Ving them seated in the Window receiving guides,and holding .theventilator in place.

To permit the ventilator to be used in vvin-l doivs of various widths the' extension plates 34C are mounted on the ends of the plates 15 and-16 in a quickly detachable manner, and 'extension plates of various lengths can thus be quickly inserted in the ends of the vertical plates sothat the total length of the ventilator can be readily changed. As shown in F ig. 5 the extension plate 34; at one end is of the same Width as the Width of the open side of the channel plate 10 so that it is slidably received in the flanges 13 and 14 of the plate 15. In this form ofconstruction the outer portion of the extension plateas indicated at 35 is of greater Width than the inner end so that the shoulders V36 areadapted toabut against the outer ends of the flanges 13 and 14 of the flat plates to determine theV positioning of this extension plate. As the extension Vplates are readily removable by merely pulling them out ofthe guide surfaces or anges in which* they are held, the substitution ofl longer or shorter platesto accommodate Windows of various Widths is very easily and quickly accomplished. i i

In Figs. 6, 7 and 8 a modied form of end plate is shown. 'The extension plate 37 is flat at its end so that it lmay be inserted between the compressibley guidestrip 31 and the metal channel 32 on the outer side of the glass, the top flange-13 being also received between the top guide strip and its metal channel. The plate 15 may have a projection or stop 38,

Which may be struckup out of the metal of.

the plate to form a stop limiting the inward movement of the extension plate and determinlngthe position of the latter with respect v to the fiat plate 15. The extension plate 37 is preferably formed with ank angular or inclined inner end or edge 39 adapted to abut against the stop 38. The plate 37 beingslidable in the flanges 13 and 14 may easily be Withdrawn and used in anY inverted position to adapt the ventilator to .Wider Window.

The' plate 37 when inverted is ofcourse prevented from moving in along the plate 15 to v hicle Window opening,

as great a depth as When positioned'as shown in Fig. 6, asfthe stop 38 is engaged by the longer side of thefeXtension plate. `'Or the short extension plate `may be replaced bya longerplate 40 asshown in 7 to adapt the ventilatorforuse in Windows of ya larger range of sizes. Y Thus by eitherre'v'ersing or inverting the extension plates or using longer plates different ranges of Window sizesmay be fitted. l i i I It Will noWUbe apparent that When lthe ventilator is positioned at the top of a yvee With theflange'd tops of the plates l5 and 16 andfthetop edges of theextension plates received in the Vtop horizontal glass guide, the closing movementsof the Window are not interferedwith, and the Window may be llowered to the bottom of the ventilator or toany position along the ventilating openings 24 to govern the amountof air entering and leaving the vehicle. The

forward motion of thevehicle thus creaties a free circulation ofair through the openings in the forward' plate 16 and the air-leaves the vehicle through thev openings in therear plate 15,7being Withdrawn from therear opening in the Ventilating passage by reasonof the rush 'of airpast this opening and the pressure created by the'air supplied to the vehicle through the-front of the ventilator. Being located at the top of the Window opening and being of a quite small 'depth in a vertical direction7 it d oes not interfere Withthe vision of the occupants of the vehicle and is out of the Way and .introduces the fresh air above the heads of the occupants of thefcar, thus avoiding objectionable drafts. Being symmetrically formed it is adapted to be iisedon the right or leftside ofthe vehicle Without rearrangement. of the parts... The channel plate 10 is preferablyprovidedjwith a stop member 46, ofV leather or otherfsuitable niaterial; lriveted in place at the "center ofthe bottom portion thereof to prevent-rattlesibetween r the Window v glass 'and the ventilator and to limit inwardmovements of the plates 1 5 andlwith respeotnto the plate ,1.0.v -`The entrance Vof moistureorrain intorthe ventilator is to some extent prevented by extending the ends of the channel plate l0 at the top portion thereof as shown at 4.5 inFigel, so that the top edge of this channel plate Which extends straight outwardly above thebottom cut-away portion acts as avshield and rain moisture are'thus prevented from dripping into the Ventilating passage. p
